This invention relates to devices for washam aware that there are many of ortable clothes washing machines operated y power,and I am aware that there are certain types ofdish washing machines which 'are not portable.

An ob ection to'the portable t pe of clothes washing machines is that it is diflicult to fill them and to empty them.. In some cases they can be filled with a hose and in some cases the Water can be drained into a pail through an outlet in the bottom, and in other cases diifer'' 'ent types of suction devices are used emptying them.

This invention relates to the type of tubs use for

known as set tubs which as ordinaril are rectangular in shape when viewe from the top, and which are setin position. Such tubs are usuall fastened to the walland as part of their equipment there are hot and cold water faucets, the water from which goes into the tub.

Many tubs have outlets at the rear-or in a corner, and some have them at the middle ofthe bottom.

The purpose of this invention is to pro vide a power washer associated with a per-;

manentlyfixed set tub having a water inlet, and an outlet at the center of the bottom for an ordinary plug so that the tub can beused for hand washing if desired, combined with a certain type of outlet through which the power drive shaft operates.

For the purpose of converting this tub into a power washing machine, I provide a special .form of packing box which extends down from the central outlet and having preferably in one side a clean out opening and in the other side a waste pipe connection which connects .with a waste'pip'e having a shut off valve. Preferably the handle of this valve extends out near the front under thetub within easy reach of the operator.

I also provide power means which gives to a vertical drive shaft a reciprocating motion. This 'drive shaft extends-up-through a water tight-bearing and terminates at v point a little below the bottom or floor o;

the tub so that the shaft does not interfere with the outlet. lug. i

I also provi e a rotor having any able form of blades'and a hub which extends down into the tub outlet'and engages the end of the drive shaft when it is desired to use the device for power washing.

Fig. 5-is a vertical sectional view of mypreferred type of packing. box Outlet.

- In the drawings, Are resents a set tub preferably of rectangular orm at the bottom 13, and having about the middle of thebottom a flush outlet 14. 1 represents a skirt or splash board which extends up on wall D at t e back of the tub and through this project one or more water inlets such as 10 and 11, each provided with a suitable shut off valve.

'B represents a drive shaft packing box which extends down from outlet 14 and has at one side a clean out opening 21 into which fit's a plug 22 and at another side a waste pipe connection 23.. I v

As shown, packing box B is attached to the bottom of the tub A by means of a thimble 5.

which extends down snugly through outlet 14 as shown at 15, and whichpreferably has an annular skirt 16. which extends out into an annular recess 6 surrounding outlet 14.

Thimble '5 is threaded at 17 to engage interior threads20 in" the top ofpacklng box B. "18' is a fastening nut with interior. threads'2 'which engage threads17 whereby the floor 13 of the tub is clamped between 16,

placking box B isa threadedhole 7 into whic washer 113 and nut 18. v

' In the bottom of is screwed the threaded art 24 of. shaft bearing 25. 28 is a central snugly passes vertically the driveshaft C.

ole through bearing 25 throu h which 26 represents an annular mercury cup which extends around the top of shaft bearing 25, such cup being filled with mercury 27.

The drive shaft C extends up through bearing hole 28 and terminates at the top end 30 which is located below the floor 13 o the tub and, as shown, is formed with a vertical slot 31 to receive a pin 42 in the downwardly projecting hub 41 of a detachable clothes washing rotor K having suitable blades 40. 4

represents an annular skirt which is h tightly fixed on drive shaft C and extends in which is a hole 44 which fits over the end of shaft C and through this passes the pin 42 adaptedto engage slot 31.

The means to give the drive shaft a reciprocating motion as shown includes a motor L which may be of the electric type and has a shaft 50 keyed to which is an eccentric 51 around which is'an eccentric strap 52 which by means of an arm 53 engages crank arm 33 of shaft C, thus iving it motion. The lower end 34 of shaft 5 rests on a thrust bearing 4 which, as shown, is fixed to the floor L.

is a shut off valve in waste pipe H operable through a shaft 71 and hand wheel 72 near the front and bottom of the tub within easy reach of the operator.

When used as a hand washing device, the rotor K is lifted off and a plug P is put in its place.

161 is a washer which I may use to help keep the shaft water tight.

As shown in Fig. 3, I may use a different type of packing box and a slightly different type of shaft.

represents 'the packing box which extends downward from a central outlet in tub floor 13, and preferably has the clean out 81 and the waste connection 82 with valve 83.

At the bottom 84, I show any kind of elastic packing 86 held in place by the packing nut which is screwed upward into 84 and has a bearing hole 87 through which passes the shaft 89 which terminates in a squared end 88 at a point below the tub bottom 13.

While I prefer to use a set tub with a rectangular floor, I may use a set tub 90 of the shape shown in Fig. 4.

The front of this tub is semi-circular and the back where it is attached to wall 91 is straight. 92 is a water inlet and 93 is a centrally disposed flush outlet from which extends a-waste pipe 95 having a shut-off valve 96 which can be operatedby a handle 97 proximate the front of the tub.

It is obvious that the rotor might be more or less permanently fixed to the drive shaft if desired. This fixing of the rotor to the drive shaft may occur if, as shown in Fig. 5, the metal of the hole 44 and the metal of the outside of shaft 30 are of steel, iron or other easily rusted material and they rust together or if the fit between these parts is a drive fit instead of a sliding fit.
